Good times indeed brother, that day was an absolute dream come true and I still cant thank you enough for being the unbelievably kind and amazing person that you are!
I've been practicing techniques, scales, some songs and chords ever since then. About pinch harmonics, I practiced them the way you taught me and I really got it after a few days of practicing just like you said! I'll post a progress video of my playing to my profile here this week.
If I am not mistaken that interlude uses a 12 string guitar. I can play like 90% of it on 6 string I think I play it quite different to the accustomed way its played.
